Our previous studies have evaluated the bioactivities of a fucoidan isolated from (SF-F). To further investigate the health benefit of SF-F, in the present study, the protective effect of SF-F against ethanol (EtOH)-induced oxidative damage has been evaluated in in vitro and in vivo models. SF-F effectively improved the viability of EtOH-treated Chang liver cells by suppressing apoptosis. In addition, the in vivo test results indicate that SF-F significantly and dose-dependently increased the survival rate of zebrafish treated with EtOH. Further research results show that this action works through decreasing cell death via reduced lipid peroxidation by scavenging intracellular reactive oxygen species in EtOH-stimulated zebrafish. These results indicate that SF-F effectively protected Chang liver cells and zebrafish against EtOH-induced oxidative damage and suggest the potential of SF-F to be used as an ingredient in the functional food industry.

Objective: This study investigated the locations of amino acid modifications within two major human hair keratins (Type I K31 and Type II K85) with probable implications for protein and hair structural component integrity. The particular focus was on cysteine modifications that disrupt intra-protein and inter-protein disulphide bonds.
Methods: Human hair was exposed to accelerated, sequential heat or UV treatments, simulating effects resulting from the use of heated styling tools and environmental exposure over a time frame approximating one year.

Background: High-density lipoprotein (HDL) function, rather than its concentration, plays a crucial role in the development of coronary artery disease (CAD). Diminished HDL antioxidant properties, indicated by elevated oxidized HDL (nHDL) and diminished paraoxonase-1 (PON-1) activity, may contribute to vascular dysfunction and inflammation. Data on these associations in CAD patients, including acute coronary syndrome (ACS), remain limited.

S-glutathionylation (SSG), a redox-sensitive post-translational modification mediated by glutathione, regulates protein structure and function through reversible disulfide bond formation at cysteine residues. Glutaredoxins (GRXs), pivotal antioxidant enzymes, catalyze SSG dynamics to maintain thiol homeostasis. Recent advances in redox proteomics have revealed that SSG dysregulation is intricately linked to neurodegenerative, cardiovascular, pulmonary and malignant diseases.
